New heart! RB style

Try using some 3M Spray Glue on your Silicone parts before assembly. Let it get really tacky before you assemble them and use a socket to tighten the hose clamps. Some guys also use Hair Spray. Clean up is easy with either one. I usually keep some Lacquer Thinner around for stuff like that. Another thing you can do is if there is enough meat, run 2 hose clamps.

If your FP is at 15 PSI I would think your float bowls would be really full and it would be running really rich pushing fuel past the needle/seat. I would try a new gauge before anything else. You are just about there and YES I am Jealous!:D
